@anustart if you simply paste the above you’ll have no change, as I believe these are the defaults for these classes. Modify the values for font-size and line-height to your liking. You may also want to add letter-spacing properties to decrease space between letters in order to fit more on one line. Example:

.medium {
font-size: 26px;
line-height: 30px;
letter-spacing: -2px;
}

If you really want to get your hands dirty, you may want to consider switching to a narrow font. (I believe RobotoCondensed is already included by default):

But that leads to a general question about the fonts :
RobotoCondensed is not in the fonts directory, they all have an addition, like RobotoCondensed-light, etc…
Does that matter ?
The main.css uses ‘Roboto Condensed’.
Again, is that difference important ?
Thanks
